fix: consider version when getting CRDs for validating descriptors

[tthvo]

Description of the change:

An additional condition is included for matching apiVersion of example CRs with CRD version when searching for the CRD in the CSV.

Motivation for the change:

Previously, the olm-spec-descriptors scorecard test failed when multiple versions of CRD are included in the CSV. The CRs specified in alm-examples annotations are validated only against the first matched CRD (by kind), which is incorrect. This ensures the CRD with correct kind and version is selected for descriptor scorecard test.
